IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent N 0. 171,081, datedDecember 14, 1875; application filed November 16, 1875.

To all whom it may concern:

Be it known that I, CHARLES E. BALL, of Philadelphia, in thecountyofPhiladelphia and State of Pennsylvania, have invented certainnew and useful Improvements in GasLamps; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification, in which- Figure 1 is a side elevation.Fig. 2is a perspective, partly broken away.

The object of my invention is to provide a gas-lamp, or lamp in whichthe light is produced by the burning of hydrocarbon oil on a Wick withcoal'gas, so constructed that there will be a perfect union of the gasand hydrocarbon vapor at the point of combustion, and a perfectlystraight and upright flame.

In carrying my invention into effect I take alamp provided with aflat-wick burner. I

then secure in any suitable manner a gasburner, so arranged that it willemit its current over the top of the wick, the top of the wick-burnerand that of the gasburner being at or about the same level, both burnersin clinin g toward each other, so that if continued they would meet orintersect.

To each burner is attached a curved shield or deflector, the purpose andeffect of which is to cause the gas-current to be held directly over thewick until wholly consumed at the point of combustion, and to cause theflame to rise straight up and maintain constantly a true verticalposition.

Referring to the accompanying drawing, A shows a hydrocarbon-fluid lamp,having a wick-burner B, curved or bent in the manner shown, andfurnished with a plate or shield, G, forming a deflector. D is agas-burner, arranged substantially as shown, inclining to- ,ward theburner B, the upper edges of each (13f said burners being at or aboutthe same eve].

To the burner D is attached a plate or shield, E, similar to 0. Theseplates 0 andE incline toward each other above the burners until theynearly meet, when they trend upward, forming vertical Walls aboutone-sixteenth of an inch apart, between which the combined flame ofvapor and gas ascends in a perfectly true and straight line. the wick.

Where a horizontal or inclined tlame is desired, the shield on thewick-burner may be taken oil or bent back so as to cause its verticalwall to lean in the wished-for direction,-

the vertical wall of the remaining shield being also similarly bent orinclined. This modification I consider within the terms of my invention.

What I claim is The deflector for a gas-lamp, composed of the inclinedplates 0 and E, attached to the wick-burner and gas-burner respectively,and terminatingat their upper extremities in vertical walls to produce amore perfect union of gas and vapors at the point of combustion, andcause the flame to ascend in a straight line without veering to eitherside, substantially as shown and set forth.

In testimony that I claim the foregoing I' have hereunto set my handthis 11th day of November, 1875.
